In addition to the nutritional values, milk has a wide range of bioactive compounds which have been found to be increasingly important for physiological and biochemical functions on human metabolism and health. Bioactive components in milk comprise specific proteins, peptides, lipids and carbohydrates. Especially, milk proteins are known to exert a wide range of nutritional, functional, and biological activities. And milk proteins are considered the most important source of bioactive peptides, including antihypertensive, antithrombotic, antimicrobial, antioxidative, immunomodulatory, and opioid peptides. Many ingredients containing specific bioactive peptides derived from milk protein hydrolysates have been launched on the market and are currently under development. In future studies more emphasis should be given to the health-promoting effect in the well-defined human clinical studies for the successful development of function foods based on the milk-derived bioactive components.

Milk contains essential nutrients and functional compounds, such as calcium, fat-soluble vitamins A, D, E, and K, carotenoids, bioactive peptides, and sphingolipids. The bioactive molecules from milk are not expensive and have an added advantage of being derived from food. Therefore, they are more stable and have a broader spectrum than that of other chemicals. Bioactive milk components are useful for treating non-digestive tract disorders, such as cancer, cognitive decline, and hypertension. However, the clinical application of certain breast milk ingredients is limited due to the lack of a large-scale production technology. Once the scaled-up production of lactoferrin became possible, clinical applications were devised and evaluated. Similarly, human alpha-lactalbumin made lethal to tumor cells (HAMLET) can be produced on a large scale as a recombinant protein in microorganisms or in transgenic cattle using suitable separation systems. HAMLET can be used to treat human skin papilloma and cancer. Studies on breast milk that explored the clinical applications of the bioactive components of breast milk have spurred the development of translational medicine and breast milk-derived therapeutics. Some breast-milk derived therapeutic agents are already available to clinicians. Many components of breast milk have shown efficacy in pre-clinical studies and have valid clinical evaluations.

Traditional Chinese Medicines (TCM) have attracted great interest in recent researchers as alternative medicines for incurable diseases. This review focuses on qualitative and quantitative analytical approaches for bioactive metabolites of components flavonoids and saponins of traditional Chinese medicines by TLC system, although various methods have been introduced. Emphasis will be put on the processes of metabolite extraction from intestinal bacterial cultures or urines, separation (mobile phase) and detection. The identified metabolites by selection of extraction solvent and detection methods are also discussed. In addition, metabolite determinations of flavonoids (baicalin, apiin, rutin, quercetin, quercitrin, kaempferol, diosmin, hesperidin, poncirin, naringin, puerarin, daidzin, daidzein, tectoridin) and saponins (ginsenosides, kalopanaxsaponins, glycyrrhizin, chiisanoside, saikosaponins, soyasaponins) in culture fluid, in urine and in some herbal formula extracts are summarized. These bioactive metabolites of these components by intestinal microflora should be connected to pharmacological actions.

The herbal components should be transformed to bioactive compounds by the intestinal bacteria and then expressed the pharmacological action of herbal medicines. Human fecal enzyme activities related to the metabolism of herbal components were measured. The metabolic activities of puerarin, poncirin, glycyrrhizin, ginsenoside Rb1 and ginsenoside Rb2 to their bioactive compounds were $3.5{\pm}1.18,{\;}333.1{\pm}183.64,{\;}95.7{\pm}107.1,{\;}20.8{\pm}10.32{\;}and{\;}20.8{\pm}13.3{\;}{\mu}mo1/h/g$, respectively. The profile of these metabolic activities of glycyrrhizin and ginsenosides were not changed even if herbal extracts, water extract of Glycyrrhizae Radix and Ginseng Radix, instead of the isolated compounds were used . All the enzyme activities tested were not different between male and female, and between ages. However, the difference of these enzyme activities in individuals was significant. These results suggest that the metabolic activity of herbal components to bioactive compounds may be a factor of constitutional classification, and could be available for constitutional classifications, if the constitutional herbal medicines were used .

The robust development of frog farming offered high economic benefits but created a large waste residue of frog bones and skin that received little attention. Over the years, inedible by-products have often been processed into biomolecules of potential value and environmental benefits, such as collagen, gelatin, and bioactive peptides. An overview of bioactive compounds on frog skins from various countries indicated that brevinin was the most abundant biological peptide found in frog skin. Other remaining compounds also possessed their highlighted activities, including antibacterial, stimulating insulin release and gastric hormone release, anti-cancer, and neuroregulatory. Notably, various components have been analyzed in the structure and sequence to give meaningful insight into clustering components related to their biological activity. This review may create a source of raw materials for the developmental research of by-products from frog skin and concomitantly reduce environmental pollution.

The characteristics of decoction water are important for the extraction of herbal drugs. In this study, the relationship between the characteristics of water and extraction efficiency of bioactive compounds from Corydalis tuber was investigated. Six different types of decoction water, including three types of mineral water from Jeju Island and three types of bottled water sold in market, were used as decoction water for the extraction of bioactive compounds from Corydalis tuber. The contents of minerals in six types of water were analyzed by ICP-AES and ICP-MS; the contents of extracted bioactive compounds were analyzed by HPLC. Multivariate analysis of variance was used to analyze the differences in total extraction and bioactive compounds extracted with six types of water. Multiple factor analysis was used to analyze the relationship among the pH, content of mineral, anion, total extractions and content of bioactive components as factors. There was a significant difference among the six types of water in the total extracts and the bioactive compounds. The results proved that the content of extracted compounds from Corydalis tuber was influenced by the types of decoction water.

To understand the role of intestinal microflora in the biological effect of functional herbs, which have been used in Korea, Japan, and China as traditional medicines, and suggest new bioactive compounds transformed from herbal constituents, the metabolic activities of the functional herb components (ginsenoside Rb1, crocin, amygdalin, geniposide, puerarin, ginsenoside Re, poncirin, hesperidin, glycyrrhizin, and baicalin) toward their bioactive compounds (compound K, crocetin, benzaldehyde, genipin, daidzein, ginsenoside Rh1, ponciretin, hesperetin, 18b-glycyrrhetic acid, and baicalein) were measured in fecal specimens. The metabolic activities of these components were $882.7{\pm}814.5$, $3,938.1{\pm}2,700.8$, $2,375.5{\pm}913.7$, $1,179.4{\pm}795.7$, $24.6{\pm}10.5$, $11.4{\pm}10.8$, $578.8{\pm}206.1$, $1,150.0{\pm}266.1$, $47.3{\pm}58.6$, and $12,253.0{\pm}6,527.6\;{\mu}mol/h/g$, respectively. No differences were found in the metabolic activities of the tested components between males and females, although these metabolic activities between individuals are extensively different. The metabolites of functional herb components showed more potent cytotoxicity against tumor cells than nonmetabolites. These findings suggest that intestinal microflora may activate the pharmacological effect of herbal food and medicines and must be the biocatalytic converter for the transformation of herbal components to bioactive compounds.
